Bommer Canyon Preserve

Nestled in the heart of Bommer Canyon Preserve is part of the old Irvine Ranch Cattle Camp. Some of the original structures exist today, adding to the rustic feel of the canyon. Bommer Canyon Preserve is also an important preservation area for many local plants and wildlife, including several endangered species. 


Trails are open for hiking, mountain biking, and horse-back riding. Please note that only some trails are open to the public for self-guided daily access while others are restricted to docent-led activities due to sensitive habitat. Dogs are not permitted on trails in the Bommer Canyon Preserve, but they are permitted on City of Irvine's Quail Hill Loop Trail. View a map and directions to Bommer Canyon Trailhead here.

Please note: The City of Irvine is in the process of rehabilitating the Bommer Canyon Preserve Cattle Camp site. Construction is expected to be complete early 2023, and reservations are unavailable at this time. Learn more about the Bommer Canyon Preserve Rehabilitation Project here.


Bommer Canyon Preserve Cattle Camp must be reserved as a whole; individual amenities within the camp cannot be rented on their own. The fifteen-acre facility includes picnic tables sheltered by a lush sycamore canopy and lots of open space. 

The park's traditional reservation season is April–October. 2023 facility reservation applications open in August, and requested reservation dates will be placed on a temporary hold for applicants until we can confirm an opening date.
